PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A penetration tester is conducting passive reconnaissance and wants to find historical snapshots of a target website to identify past vulnerabilities or hidden endpoints. Which online service should the tester use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Wayback Machine
The Wayback Machine (archive.org) is the correct choice because it archives historical snapshots of websites, allowing a penetration tester to review past versions of a target site to identify previously exposed vulnerabilities, hidden endpoints, or outdated configurations. This aligns with passive reconnaissance, as the tester does not interact directly with the live target.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse passive reconnaissance tools like Shodan or Censys (which focus on live infrastructure) with the Wayback Machine, which is specifically designed for historical web content retrieval.
Detailed technical explanation
How to think about this question
The Wayback Machine uses a crawler to fetch and store HTTP responses, including HTML, CSS, JavaScript, and images, at various points in time. A tester can use the `https://web.archive.org/web/*/example.com` URL pattern to list all snapshots, and even download specific archived pages via the `https://web.archive.org/web/20210101000000/example.com` format. This can reveal old API endpoints, commented-out credentials, or deprecated software versions that are no longer visible on the live site.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
